Description
TLC=Tref+α×(Tenv−Tref)
(上記式中、Tenvは環境温度を示す値、αは0.6≦α≦0.8の正数、Trefは環境温度値Tenvと温度設定信号TLCとが等しくなる温度を示す)
に従って、−40°C〜+85°Cの使用環境温度幅全体に亘って、光の波長変動をCWDM方式の波長グリッド相当の10nm以下に抑えるように、連続的に規定することを特徴とする。
TLC=Tref+α×(Tenv−Tref) …(1)
(上記式中、αは、1未満の正数、Trefは、環境温度とレーザダイオード設定温度とが等しくなる温度を示す)
|Tref+α×(Tenv−Tref)−Tenv|≦50°C
すなわち、
1−50/|Tref−Tenv|≦α
とする必要があるので、αの好適な値として、α≧3/5が導かれる。Trefは上記したように、環境温度Tenvとレーザダイオードの温度設定TLCとが等しくなる温度である。上記式は、Trefとして、例えば−40°C、あるいは+85°Cといったような極限的な値も含んでいる。Trefとして通常設定される10°C〜40°Cを想定した場合には、αの好ましい値としてα≧2/5が得られる。
